Summary The complexity of the geological conditions in the places where the wells are currently drilled, as well as a set of tasks to be solved by teams of drilling experts and the challenges to radically increase the efficiency of operations under low oil prices – all these challenges require a comprehensive engineering approach to real-time support of well drilling. Regarding development of complex high-risk projects with a high degree of uncertainty, an emphasis should be made on creating and using a unified integration platform for various disciplines involved in the drilling process and real-time interaction. A single unified petrophysical & geosteering simulation environment will make it possible not only to solve the issue of increasing the efficiency and safety of well drilling, but also boost further improvement of the automatic on-line interpretation of log data for drilling horizontal wells. The article provides basic steps to designing and building a combined model, real use cases, evaluations of implementation efficiency and possible ways of development the methods proposed.

One of the methods of extraction of remaining reserves used in JSC “Gazpromneft-Noyabrskneftegaz” is sidetrack operations which also enable to involve fishing well stock of oil fields. Efficiency of these arrangements depends mainly on cooperation of specialists in geology, field development and drilling. At present, interaction pattern between subdivisions of the Company and contractor drilling organizations is developed which allows to perform full cycle of implementation of sidetracks starting with selection of wells and finishing geological support of drilling operations. Permanent field development monitoring of perspective oil deposits, application of the developed well selection technique and analysis of geological features using state- of-the-art program packages of seismic interpretation, geological and simulation modeling packages encouraged successful drilling jobs in the selected wells, getting agreement of actual flow rates and forecast and, as a result, increase of incremental oil production of the Company.
